  DRIVING SAFELY 
 
 
Electric parking brake 
 
 
Manual application/release    
Automatic application/release 
   
Before leaving the ve-
hicle, check that the 
brake warning lamp in 
the instrument panel 
and the  P 
 warning lamp in the control 
lever  A 
 are  on fi xed (not fl ashing) 
.     
Manual application 
 of the parking 
brake is possible by  pulling 
 the control 
lever  A 
. 
  With the ignition on,  manual release 
 of 
the parking brake is possible by  press-
ing the brake pedal 
 and  pulling then 
releasing 
 the control lever  A 
.    Press the accelerator pedal and let the 
clutch pedal up (manual gearbox), the 
parking brake is released automatically 
and progressively as you move off. 
  With the vehicle at rest, on switching off 
the engine the parking brake is applied 
automatically. 
   
 
  
 147  
 
    With the engine running, on 
opening the driver's door there 
is an audible warning; apply the 
parking brake manually. 
  Do not leave a child alone inside 
the vehicle with the ignition on; 
they might release the parking 
brake.    If you are towing a trailer or car-
avan or if the slope might vary 
(transport on a ferry, lorry, tow-
ing...) make a maximum manual 
application with a long pull on 
the control lever  A 
 to immobilise 
the vehicle.    If this warning lamp is on in the 
instrument panel, the  automat-
ic application/release 
 is  de-
activated 
; apply and release 
the parking brake manually.

Switch off the headlamps and front 
foglamps when the level of light does 
not require their use.  
   
Avoid running the engine before mov-
ing off, particularly in winter; your ve-
hicle will warm up much faster while 
driving.  
   
As a passenger, if you avoid connect-
ing your multimedia devices (fi lm, mu-
sic, video game...), you will contribute 
towards limiting the consumption of 
electrical energy, and so of fuel. 
  Disconnect your portable devices be-
fore leaving the vehicle.  
 
 
 
Limit the causes of excess 
consumption 
   
Spread loads throughout the vehicle; 
place the heaviest items in the bottom 
of the boot, as close as possible to the 
rear seats. 
  Limit the loads carried in the vehicle 
and reduce wind resistance (roof bars, 
roof rack, bicycle carrier, trailer...). Use 
a roof box in preference. 
  Remove roof bars and roof racks after 
use.  
   
At the end of winter, remove snow 
tyres and refi t your summer tyres.  
 
 
 
Observe the recommendations 
on maintenance 
   
Check the tyre pressures regularly, 
when cold, referring to the label in the 
door aperture, driver's side. 
  Carry out this check in particular: 
   
 
-   before a long journey, 
   
-   at each change of season, 
   
-   after a long period out of use.  
  Don't forget the spare wheel and the 
tyres on any trailer or caravan.  
   
Have your vehicle serviced regularly 
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.  
 
 
   
When refuelling, do not continue after 
the 3 rd  cut-off of the nozzle to avoid 
any overfl ow.  
   
At the wheel of your new vehicle, 
it is only after the fi rst 1 800 miles 
(3 000 kilometres) that you will see 
the fuel consumption settle down to a 
consistent average.

accompanied by 
a message.    A minor malfunction has 
occurred for which there is 
no specifi c warning lamp.   Identify the malfunction by reading the 
message displayed in the screen, such 
as, for example: 
   
 
-   the opening of the doors, boot or 
bonnet, 
   
-   the engine oil level, 
   
-   the remote control battery, 
   
-   the tyre pressures,  
 
-   saturation of the particle emission fi lter on 
Diesel vehicles (see "Checks - § Checks/
Particle emissions fi lter").  
 
For any other malfunctions, contact a 
CITROËN dealer or a qualifi ed workshop.

signal and message are repeated with 
increasing frequency as the fuel level 
drops towards  "0" 
. 
  Fuel tank capacity: approximately
  60 litres 
. 
  Never continue to drive until you run 
out of fuel, as this could damage the 
emission control and injection systems.

Engine oil level indicator 
 
The vehicle must be on level 
ground and the engine must 
have been off for more than 
30 minutes for this level check to 
be accurate.    
Oil level correct  
  This is indicated by the fl ashing  of 
  "OIL" 
 or the display of a specifi c  mes-
sage in the instrument panel, coupled 
with the service warning lamp and ac-
companied by an audible signal. 
  If the low oil level is confi rmed by a 
check using the dipstick, the level must 
be topped up to avoid damage to the 
engine.     
Oil level indicator error 
   
Dipstick 
  Refer to the "Checks" section to locate 
the dipstick and the oil fi ller cap on your 
engine.     
Oil level incorrect   This is indicated by the fl ashing  of 
  "OIL --"  
or the display of a specifi c mes-
sage in the instrument panel. Contact a 
CITROËN or a qualifi ed workshop.  
  There are 2 marks on the 
dipstick: 
   
 
-   A  
= max; never exceed 
this level (risk of dam-
age to the engine), 
   
-   B  
= min; top up the level 
via the oil fi ller cap, us-
ing the correct grade of 
oil for your engine.  
 
    This information is displayed for a few 
seconds when the ignition is switched 
on, at the same time as the service in-
formation.
